Hi can anyone help recommend the best option for ceiling hairline cracks like in the picture. many thanks for the advice.
Btw you wouldn’t suggest a filler instead? Just saw the price on this stuff. I was thinking using the right filler then paint over
Push the ceiling boards either side of the cracks, at several places along the length - any movement in the boards ? If yes - then that’s the first step to fix
Even if they’re a board join they’re too fine to need filling. If you really want to you can but you’ll need to make them worse first. Cut a V following the crack. Then fill using Toupret. It’s also expensive. Waste of time though. Just use the Polycell. Cheaper than doing it twice when it cracks again, which it will. If you have loads to do then just paint the cracks and a good few inches either side and then paint over it with a quality matt white ceiling paint.
